Yes! The BV 450, BV 500 and Garcia 812 all fit horizontally in the Lightning 60 and Thunder 50/70 backpacks. The BV 450 also fits in the Lightning 45 backpack.

The torso length is the length of a person's back, measured from the hip to the shoulder, and is an important factor in the fitting process of a backpack.

Depending on the volume of the backpack and its intended use, the suspension system of a backpack becomes a key criterion. Determining back length is not as critical for shorter hikes or everyday backpacks, but is crucial for expedition, trekking and touring backpacks. With these backpacks, the pack weight can only be optimally transferred to the hips if the back length and suspension system are correctly matched.

The center of the hip belt is ideally located on the hip bones (upper edge of the pelvis) and the sacrum to carry most of the load, especially with large internal frame backpacks. There are exceptions where a shorter backpack length is better, such as in alpine situations, because this allows a shorter overall length of the backpack suspension system to allow easier access to the climbing harness.

To determine your back length, use a tape measure to measure the distance from the top of your shoulders to the top of your hip bone (pelvic rim). This is best done by a friend who can properly place and read the tape measure on your back. Any EXPED retailer should also be able to help you determine your back length.

The EXPED backpack line includes both waterproof and weatherproof models. Waterproof means these backpacks keep water out unless submerged in water. Weatherproof means that the fabric and seams are completely waterproof, but zippers and hydration ports are water resistant and not 100% waterproof.


All other backpacks in the EXPED line have coated fabrics to prevent water penetration. These backpacks do not have taped seams. Typically, other features such as durability or weight reduction are the focus of these products and are designed to be used with our waterproof drybags to keep the contents dry.


Waterproof Models: Whiteout, Black Ice, Torrent, Work and Rescue, Typhoon, Kids Typhoon, Cloudburst, Splash, Stormrunner, Tempest


Weatherproof models: Serac, Icefall, Mountain Pro, Cascade



All backpack fabrics used by EXPED are by definition "waterproof" due to their coating and have a water column of at least 1500 mm. The distinction therefore relates primarily to construction and processing:


In "water-resistant" backpacks, water can enter the backpack through the seams and through the zippers.


We define "weatherproof" as backpacks with a water column of at least 3000 mm, which also have water-repellent zippers to the main compartment and seam-taped seams. Although the zippers are very water repellent, water can enter through the zipper during heavy rains.


Our backpacks labeled "waterproof" have a water column of 3000 to 10'000 mm, are also seam sealed or welded, but use water repellent zippers only on exterior compartments, not on the main compartment. The main compartment of these models have a waterproof seal by means of a roll top. In these models, we do not refer to exterior compartments with zippers as "waterproof", but only as "weatherproof". No rule without exception: A 100% waterproof Drysuit zipper is used on the Tempest Duffles.


EXPED measures the volume of its packs using standardized plastic balls. The volume declarations are exact. The external dimensions are measured at the widest point. Calculating volume based on dimensions can lead to different values.

We recommend running the hydration tube between the main compartment and the lid (e.g. with slightly open roll-top). Alternatively the bladder can be placed under the lid when the roll-top is closed.

Mechanical abrasion, cuts, tears, burn holes, rodent bites as well as damage through drag-and-drop are not covered by warranty. In most cases these issues can be repaired at a moderate cost.

Storage of a backpack in humid conditions or wet gear in a pack can lead to hydrolisis and delamination of the PU coating. This is not covered by warranty and cannot be repaired.

The shoulder straps and hip belts are shorter on the women's model than on the men's model, and in some cases the suspension system is narrower and/or shorter. Details can be found at the respective model. Of course, women's models can also be worn by men and vice versa.

Manufacturing defects of seams are covered by our 5-year limited warranty. Seams damaged through use do not fall under warranty but can be repaired at a moderate cost.

Zipper failure does not fall under warranty, especially if improperly used or not maintained regulary. Zippers should be kept clean. In most cases we can repair or replace damaged zippers for a reasonable cost.

Backpacks (this is not brand specific!) should never be washed in washing machines or dried in a tumble dryer as this can lead to permanent damage of the fabrics and the PU coating . A further problem is that detergent residue and fabric softeners can damage the coating. We recommend washing your backpack by hand in warm water using pH-neutral soap, baby shampoo or shower gel. Stains can be removed with a soft brush. Air dry thoroughly (no direct sunlight or heat source) and store in a dry place.
